Older children verify adult claims because they are skeptical of those claims     

Samantha Cottrell  Eric Torres  Paul L. Harris  Samuel Ronfard 《Child development》2023,94(1):172-186

We investigated children's information seeking in response to a surprising claim (Study 1, N = 109, 54 Female, Range = 4.02—6.94 years, 49% White, 21% Mixed Ethnicity, 19% Southeast Asian, September 2019—March 2020; Study 2, N = 154, 74 Female, Range = 4.09—7.99, 50% White, 20% Mixed Ethnicity, 17% Southeast Asian, September 2020—December 2020). Relative to younger children, older children more often expressed skepticism about the adult's surprising claims (1-year increase, OR = 2.70) and more often suggested exploration strategies appropriate for testing the specific claim they heard (1-year increase, OR = 1.42). Controlling for age, recommending more targeted exploration strategies was associated with a greater likelihood of expressing skepticism about the adult's claim.  相似文献   

Oxygen uptake kinetics in children and adults after the onset of moderate-intensity exercise     

Samantha G. Fawkner  Neil Armstrong  Christopher R. Potter  Joanne R. Welsman 《Journal of sports sciences》2013,31(4):319-326

The literature suggests that the oxygen uptake ( V O 2 ) response to the onset of moderate-intensity exercise may be both mature from childhood and independent of sex. Yet the cardiorespiratory response to exercise and the metabolic profile of the muscle appear to change with growth and deve . lopment and to differ between the sexes. The aim of this study was to investigate further changes in the V O2 kinetic response with age and sex. Participants completed a series of no less than four step change transitions, from unloaded pedalling to a constant work rate corresponding to 80% of their previously determined ventilatory threshold. Each participant's breath-by-breath responses were interpolated to 1 s intervals, time aligned and then averaged. A single exponential model that included a time delay was used to analyse the averaged response following phase 1 (15 s). Participants with parameter confidence intervals more than - 5 s were removed from the sample; the results for the remaining 13 men and 12 women (age 19-26 years), 12 boys and 11 girls (age 11-12 years) were used for statistical analysis. Children had a significantly shorter time constant than adults, both for males (19.0 - 2.0 and 27.9 - 8.6 s respectively; P ? 0.01) and females (21.0 - 5.5 and 26.0 - 4.5 s respectively; P ? 0.05). There were no significant differences in the time constant between the sexes for either adults or children ( P > 0.05). A significant relationship between the time constant and peak V O 2 was found only in adult males ( P ? 0.05). A shorter time constant in children may reflect an enhanced potential for oxidative metabolism.  相似文献   

Fundamental motor skills: A systematic review of terminology     

Samuel W. Logan  Samantha M. Ross  Keanu Chee  David F. Stodden  Leah E. Robinson 《Journal of sports sciences》2018,36(7):781-796

The three aims of this systematic review are to describe: (1) use of the term fundamental motor/movement skills (FMS) in published articles; (2) the quality of definitions; and (3) relative use of process- and product- oriented assessments to measure FMS. The inclusion criteria included: (a) peer-reviewed article, (b) printed in English, (c) published between January 2000 and 31 December 2015, (d) presence of either the term “fundamental motor or movement skill” in the title and/or abstract, and (e) FMS were a measured outcome. There has been an increase in the number of publications on FMS in recent years, with the majority of studies conducted in Australia (n = 41, 33%). Approximately 24% of studies (n = 30) did not provide any explicit definition of FMS. A majority of studies reported the use of process-oriented measures (n = 98, 79%) compared to product-oriented measures (n = 23, 19%), and few studies used both (n = 6, 5%). We recommend that researchers provide: (1) an operational definition of FMS that states FMS are the “building blocks” (or similar terminology) of more advanced, complex movements; (2) specific categories of skills that compose FMS; and (3) at least one specific example of a FMS.  相似文献   

Evaluation of distance learning delivery of health information management and health informatics programmes: a UK perspective     

Urquhart C  Chambers M  Connor S  Lewis L  Murphy J  Roberts R  Thomas R 《Health information and libraries journal》2002,19(3):146-157

The aim of the article is to review evaluations of distance learning programmes in health information management, in order to identify the critical success factors for such programmes and discuss future directions. The emphasis is on the UK experience, based partly on reflections on the experience of one programme at University of Wales Aberystwyth (now over 10 years old), and partly on a policy review conducted for the NHS Information Authority and the NHS Information Policy Unit. The methods are, as far as possible, those of a systematic review of existing research, with, additionally, an overview of relevant policy developments for lifelong learning. The topics covered include the aims, objectives and educational philosophies of the programmes. The evidence, combined with the UWA experience, indicates the importance of face-to-face interaction, to complement distance or virtual learning. A student-centred approach to curriculum design and delivery is essential.  相似文献   

‘Observation has set in’: comparing students and peers as reviewers of teaching     

Mark Huxham  Jenny Scoles  Ursula Green  Samantha Purves  Zoe Welsh  Andrew Gray 《Assessment & Evaluation in Higher Education》2017,42(6):887-899

Peer review is a powerful method to enhance teaching in higher education. Peers, however, may not be the most relevant people in evaluating teaching success; as the most important stakeholders in learning, students’ evaluations need to be heard. Whilst some efforts to capture ‘the student voice’ are simplistic and may foster consumerist approaches, adopting ‘radical collegiality’ towards students may provide the benefits of peer review whilst avoiding some of its disadvantages. Here we describe the Students as Colleagues project, which trained student volunteers as evaluators of teaching. To assess the ability of students to provide useful reviews, we compared their evaluative feedback with that from academic peers, using a paired design and qualitative and quantitative data. Students gave significantly more positive comments, and just as many negative and directive comments, as academic peers. Student colleagues emphasised the positive personal (rather than professional) capacities of their reviewees, encouraged expressed vulnerability and drew on their broad experiences as students rather than from professional perspectives. Participation changed how students saw their abilities and helped ‘humanise’ both the reviewees and the university as a whole. Our results and standpoint theory suggest that students’ evaluative feedback is the most valuable perspective to inform teaching enhancement.  相似文献   

Examining the relationship among student perception of support, course satisfaction, and learning outcomes in online learning     

Sang Joon Lee  Sandhya Srinivasan  Trudian Trail  David Lewis  Samantha Lopez 《The Internet and Higher Education》2011,14(3):158-163

Support for student learning is a key element in optimizing student learning experiences in any learning environment and its importance has been widely discussed. This study looked at student support, particularly in the course context, focusing mainly on guidance provided to students within a course. Three categories of support were identified and used for the purpose of this study: instructional, peer, and technical support. A total of 110 students completed an online survey on students' perceptions of support and course satisfaction in an undergraduate online course at a large southeastern university. The results showed perceived support was significantly related to their overall satisfaction of the online course. The findings of this study suggest that teachers should communicate what types of support are available to students and provide an easy way of accessing and taking advantage of the support.  相似文献   

Easing the transition of first year undergraduates through an immersive induction module     

Rebecca Turner  David Morrison  Debby Cotton  Samantha Child  Sebastian Stevens  Patricia Nash 《Teaching in Higher Education》2017,22(7):805-821

Entry into higher education (HE) is recognised as a challenging time for undergraduates as they negotiate the norms and practices of new academic communities and foster relationships with peers and academics. Given the significance of this time period, our University has piloted a new four-week module that immerses students in their discipline and provides them with the academic skills and networks to support them through this period and beyond. Here we report a comprehensive evaluation examining academic and student experience of this immersive module. We explore its impact on essential aspects of the transition experience e.g. social integration, academic literacies and the sense of preparation for HE. Whilst this new approach did have positive impacts on students’ sense of integration, questions were raised around the extent to which it matched or even raised expectations, and the extent to which this prepared students for the rest of their studies.  相似文献   

OER and the value of openness: implications for the knowledge economy     

Samantha Bernstein 《Globalisation, Societies & Education》2015,13(4):471-486

The knowledge economy is marked by recent trends in technological advancement, globalisation and increasing knowledge intensity. Through new technologies like Open Educational Resources (OER), knowledge can be freely accessed by individuals around the world, blurring traditional notions of ownership and prompting a social transformation manifested through values based on open knowledge access. This paper examines the extent to which values of openness are at odds with the capitalist frameworks underlying the knowledge economy and considers whether the influence of openness is transitory or whether a new capitalism must evolve in order to support social forces based on these values.  相似文献   

Anthropometric and physical performance characteristics of top-elite,elite and non-elite youth female team handball players     

Samantha Louise Moss  Nicola McWhannell  Lars Bojsen Michalsik  Craig Twist 《Journal of sports sciences》2015,33(17):1780-1789

In order to maximise the potential for success, developing nations need to produce superior systems to identify and develop talent, which requires comprehensive and up-to-date values on elite players. This study examined the anthropometric and physical characteristics of youth female team handball players (16.07 ± 1.30 years) in non-elite (n = 47), elite (n = 37) and top-elite players (n = 29). Anthropometric profiling included sum of eight skinfolds, body mass, stature, girths, breadths and somatotype. Performance tests included 20 m sprint, counter-movement jump, throwing velocity, repeated shuttle sprint and jump ability test, and Yo-Yo Intermittent Recovery Test Level 1. Youth top-elite players had greater body mass, lean mass, stature, limb girths and breadths than elite and non-elite players, while only stature and flexed arm were higher in elite compared to non-elite players (all P < 0.05). Sum of skinfolds and waist-to-hip ratio were similar between groups (P > 0.05). Top-elite performed better in most performance tests compared to both elite and non-elite players (P < 0.05), although maximal and repeated 10 m sprints were similar between playing standards (P > 0.05). Elite outperformed non-elite players only in throwing velocity. The findings reveal that non-elite players compare unfavourably to top-elite international European players in many anthropometric and performance characteristics, and differ in a few characteristics compared to elite European club team players. This study is useful for emerging team handball nations in improving talent identification processes.  相似文献   

Report to the President on the Use of Technology to Strengthen K–12 Education in the United States: Findings Related to Research and Evaluation

The Panel on Educational Technology was organized in April 1995 under the auspices of the President's Committee of Advisers on Science and Technology (PCAST) to provide advice to the President on matters related to the application of information technologies to K–12 education in the United States. Its findings and recommendations were set forth in March 1997 in the Report to the President on the Use of Technology to Strengthen K–12 Education in the United States. This report was based on a review of the research literature and on written submissions and oral briefings from a number of academic and industrial researchers, practicing educators, software developers, governmental agencies, and professional and industry organizations involved in various ways with the application of technology to education. Its most important finding is that a large-scale program of rigorous, systematic research on education in general and educational technology in particular will ultimately prove necessary to ensure both the efficacy and cost-effectiveness of technology use within our nation's K–12 schools. Finding that less than 0.1 percent of our nation's expenditures for elementary and secondary education are currently invested to determine which educational techniques actually work, and to find ways to improve them—an extremely low level relative to comparable ratios within the private sector—the Panel recommended that this figure be increased over a period of several years to at least 0.5 percent, and sustained at that level on an ongoing basis. Further, because no one state, municipality, or private firm could hope to capture more than a small fraction of the benefits associated with a significant advance in our understanding of how best to educate K–12 students, the Panel concluded that such funding will have to be provided largely at the federal level in order to avoid a systematic underinvestment (attributable to a classical form of economic externality) relative to the level that would be optimal for the nation as a whole. This paper originally appeared as Section 8 of the report.  相似文献
